Reboot All Network Equipment

Reboot means to turn the networking devices off (i.e. unplug them from the power source), and then to turn them back on after a set period of time. This will allow the network devices to refresh their settings.

Please reboot all of your network equipment, including any Wireless access points, routers, Voice Over IP (VOIP) modems, and broadband modems for two full minutes. After two minutes, you can turn on (or plug in) your equipment.

Check your Environment

Make sure to allow adequate ventilation to flow from the PlayStation 3 system's vents (i.e. avoid obstructing the vents etc.).

Make sure to keep the PlayStation 3 system away from excessive dust, smoke, steam, extreme temperatures, humidity, or direct sunlight.

See the PlayStation 3 system Safety and Support guide for full details on Safety Precautions and Use and Handling.

Restore Default Settings

During certain troubleshooting situations, it may be necessary to restore all of the PlayStation 3 system settings back to their original default configuration.

Once you select Restore Default Settings, you will see a list of settings that will be restored. Scroll through them and press (X button) to restore the settings.

After the operation is complete, you will see the initial set-up screen that appeared the first time you turned on the PlayStation 3 system.
You will need to go through the initial set-up process before you can use the PlayStation 3 system.

Note:

The Restore Default Settings feature will erase any previously saved settings and restore all of the following settings to the default:

BD/DVD Settings

Music Settings

Chat Settings

System Settings

Date and Time Settings

Accessory Settings

Display Settings

Sound Settings

Security Settings

Network Settings

Internet Browser Settings

Also, do not confuse Restore Default Settings with the Restore PlayStation 3 System option (the next option down on the menu). The Restore PlayStation 3 System option will not only restore the default settings, but it will also delete all hard disk content. (You will lose all saved content from your PlayStation 3 system's hard drive if you use Restore PlayStation 3 System.)
